TRANSMISSION PLANNING & DEVELOPMENT

National Grid is comprising Inter-State (ISTS) and intra-State Transmission ( STUs) systems.

Power system planning has been aligned with the Transmission Planning Criteria (n-1/n-1-1 contigency), EA,2003, National Electricity Policy, Tariff policy, Electricity Grid Code, Regulations and market orientation of the Electricity Sector.

Transmission exercises are carried out in-coordination by CEA, CTU, STUs & other Stakeholders – system finalization & review at Regional Standing Committee on Power System Planning.

Transmission System Development followed on Tariff Based Competitive Bidding (TBCB) Policy-Inter State (5-1-11) & Intra-State(5-1-13)

Transmission charge recovery mechanism is based on Point of Connection (PoC) Tariff methodology

Transmission system Plans for evacuation of 9 coal fired UMPPs (each of 4000MW) at Tilaiya(Bihar), Sasan(MP), Mudra (Gujarat), Krishnapatnam (AP), Chattisgarh(RfQ),Orissa(RfQ), Cheyyur (TN), Karnataka are on the horizon.

Evolved Master Transmission Plans to harness hydro potential in North eastern region and northern region of the country.

For additional import beyond 50 MW by Nepal, Nepalneeds to tie-up directly from Indian Electricity marketthrough licensed electricity traders such as PTC oncommercial basis, and its tariff would be beyond thepurview of the Power Exchange Committee. Nepalprocures 20-25 MW from India market through PTC.

Through the 132 kV Tanakpur-Mahendranagar S/Cline 70 MU free power from Tanakpur HEP (120 MW) issupplied to Nepal under the Mahakali treaty. Presently,Nepal is drawing about 109-210 MW from India.

ADDITIONAL SYSTEM STRENGTHENING FOR

SUPPLY OF POWER TO NEPAL

MW to Nepal MEA is being implemented through WAPCOS(expected by

August 2015).

As a part of Agreement between government of Nepal and Government of the

India on Electric Power Trade, cross Border Transmission Inter-Connection and

Grid Connectivity , the Joint Working Group and Joint Study Committee

was formed.

JWG and JSC decided for preparation of a long term integrated transmission

plan for evacuation of power from the hydro Power Stations in Nepal like Arun-

III HEP (4x225MW) by M/s. SJVNL, Upper Karnali (900 MW) and Upper

Marsyangdi (600 MW) HEPs by M/s GMR, India and related Cross border

inter-connections between the two countries.

The perspective plan will cover the generations likely to come up by 2035 and a

detailed action plan will be prepared for the projects coming up to 2025.

A Joint Technical Team (JTT) comprising of experts from Nepal and India has

been constituted to look into this issue.

Indo-Bhutan

Interconnection

EXISTING CROSS BORDER TRANSMISSION SYSTEM

ASSOCIATED WITH THE HEPS IN BHUTAN

India and Bhutan have terms of cooperation for exchange

of power between the two countries. Bulk of power

generated at Hydro Electric Projects at Chukha

(336MW), Kurichu (60MW) and Tala (1020MW) in

Bhutan, is exported to India after meeting the internal

demand of Bhutan.

The associated cross-border transmission systems for

evacuation and transfer of power from these HEPs has

been developed and is operated in synchronism with the

Indian Grid.

Royal Government of Bhutan (RGoB) has embarked on to

harness its huge hydro potential and identified about 75

nos. new HEPs by 2030 at various river basins.

About 26534 MW hydro potential would be harnessed by

2030 and out of this, 10334 MW hydro power

developments from 14 nos. HEPs have been envisaged to

be implemented during 2020.

Most of the future generation in Bhutan would be also

exported to India, after meeting the internal demand of

Bhutan.

Considering the above scenario, National Transmission

Grid Master Plan (NTGMP) for Bhutan has been evolved

by carrying out comprehensive power system studies.

Planned/under-construction Cross border

Transmission links associated with HEPs in Bhutan

RGoB is in the various phases of developing over 10 GWhydro potential by 2020 of which Punatsangchhu-I(1200MW), Punatsangchhu-II (1020MW) and Mangdechhu(720 MW) HEPs are ongoing Projects.

The ATS for the above three HEPs according to theNTGMP Plan is under construction.

India-Sri Lanka

interconnection

Cross-Border link/proposal

Memorandum of Understanding has been signed among

Govt. of India, Govt. of Sri Lanka, PGCIL and Ceylon

Electricity Board on 9th June 2010 for carrying out

feasibility study for interconnection of India–Sri Lanka

Electricity Grid.

POWERGRID, India and CEB, Sri Lanka has been

appointed as executive agencies for the above project.

1000MW, ±400kV HVDC bi-pole line from India (Madurai) to

Sri Lanka (Anuradhapura): 360km

Indian Territory (Scope : POWERGRID) Madurai to Panaikulam

: 130km

Sea Route (Scope: POWERGRID) Panaikulam (India) to

Thirukketiswaram(SL): 120km

Sri Lankan Territory (Scope: CEB) Thirukketiswaram to

Anuradhapura(New) : 110km

ADDITIONAL OPTION

In a meeting between the officials of India and Sri Lanka regardingFeasibility Study for interconnection of India-Sri Lanka Electricity Grids,it was decided that all possible efforts would be made to reduce the cost ofthe project so as to make it economically viable. It was decided to work onthe following measures:

i. Reduction in length of Submarine Cable

ia. Termination of Cable at Talaimannar in Sri Lankan Territory in place of Thirukketiswaram. This would reduce the cable length by about 30km.

ib. Termination of Cable near Dhanushkodi (at Setu Samudrum crossing) in Indian Territory in place of Panaikulam. This would reduce the cable length by about 45km, however would involve extensive use of pile foundation for line towers.

ii. Explore possibility of reduction of HVDC terminal Cost

iii. To consider multilateral funding for carrying out cost estimate

It was also decided that the revised cost would be carried out for 2x500MW HVDC (Conventional as well as VSC) bipole line to be implemented in two stages.

ADDITIONAL OPTION

The revised route for the interconnection line would be as follows:

2x500MW HVDC bipole line from India(Madurai) to Sri Lanka (Anuradhapura-New): 370km

Overhead(India) : Madurai to near Dhanushkodi : 180km

[ The Transition station for interface connection point between HVDC overhead lines and submarine cables in Indian Territory would be located in the sea near Dhanushkodi after crossing of setu samudrumroute.]

Submarine Cable : Dhanushkodi (India) to Talaimannar (Sri Lanka) :40km

Overhead(Sri Lanka) : Talaimannar to Anuradhapura(New) : 150km

The remaining scope of work would remain unaltered.

PGCIL / CEB has completed the technical study and various financial options.PGCIL is working on a revised proposal including the under sea cableconnectivity to bring the cost down and make the project viable.

India- Pakistan

Interconnection

CROSS-BORDER LINK/PROPOSAL

At present, no transmission link is existing between India and Pakistan. Pakistan grid is at 500kV AC whereas the voltage adopted in the Indian grid is 400kV and 765kV AC.

For establishment of a cross border link to enable to supply about 500MW fromIndia to Pakistan on commercial basis a 400kV D/C AC inter-connectingtransmission line between Amritsar (India) and Lahore (Pakistan) with 500MWHVDC back to back converter station at Lahore has been prima-facie identified.

In the third meeting of the Expert Groups between held on 5th March 2014 inNew Delhi, Pakistan side desired to initially draw power at 220 kV by chargingthe proposed 400 kV D/C line at 220 kV till the time HVDC converter station atLahore gets established (it is yet to be firmed up).

It was also proposed by Pakistan side that a Joint Technical Team comprising of four sub-groups would be formed and the composition of JTT and sub-groups and their scope of works, deliverables, time lines and nominations would be finalized.

High Commission for Pakistan has recently forwarded a draft MoU and aproposal for formation of four subgroups to MoP. As a follow up action, MoP hasconstituted a JTT comprising 6 members and a technical sub-group comprising 3members from the Indian side vide its letter dated 24th June, 2014, forpreparation and submission of first report on cross border interconnection withterminal locations etc..

India –Afghanistan

TRANSMISSION WORKS

220 kV DC Kabul - Pul-e-Khumri 200 km. (approx) transmission line with 220/110/20 kV S/S at ChimtalaSub-Station was constructed by POWERGRID on May’ 2009

The assets have been taken over by MEW, Afghanistan in the month of March 2012.

Further, for construction of 220/20 kV Doshi and Charikarsubstations in Afghanistan, award was placed on M/S. BHEL by POWERGRID on October 21, 2011. The project is expected to be completed within two years from the date of Government sanction for the project, i.e. by October 2013.

GoI is also constructing Salma PH (14x3 MW) with 110 kV transmission line from Salma – Haret (160 Kms. Appox.) through WaPCos.
